Description

200922346 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a wireless communication system, and more particularly to a Worldwide Interoperability f〇r Microwave Access (WiMAX) (IEEE 80 2.16a) system. And a wireless end and wireless base station for the system. WiMAX(R) is a standard for wireless communication technology and is a common term used for standardization techniques developed by the IEEE 802.16 working group. The WiMAX Forum (R) is an industrial organization. [Prior Art] Compared to the downlink (D〇wn Unk) communication, the communication area of the current WiMAX system is more similar to the uplink communication (Up li nk ) communication. This is because the transmission power between the 1 MAX base station and the embedded w丨ΜΑχ wireless end is caused by the asymmetry of transmission and reception timing.

As shown in Figure 1, the WiMAX base station (BS) receives code division multiplexing from the embedded wlMAx wireless end (MS) (c〇de Divisi〇n Muitipie)

Access, CDMA) Ranging Request and inform the pull-in WiMX wireless end of individual adjustments for power, timing and frequency in the ranging response. When individual power, timing, and frequency parameters are within the permissible range, the % ΜΑχ base station informs the embedded TM that the wireless end ranging is complete in the ranging response.

The terminal repeatedly transmits the CDMA ranging request to the WiM base station a predetermined number of times to refer to the adjustment value of the base station in the ranging response notification until the wlMAX base station notifies the human wiM wireless terminal measurement (four). In this terminal, the individual power's timing and frequency are adjusted separately. 2138-9878-PF 200922346,,: When the number of times is not adjusted for any parameter value, the W i ΑΧ ΑΧ 7 can not notify the embedded WlMAX wireless terminal ranging completion. If you can't adjust the number of worms, then the network entry fails, so that the embedded WiMAX, „, 线, ^ can't get the down link or the up link service. ^The individual parameters can't be adjusted by the predetermined number of times. One reason for being adjusted to (3) within the scope of the ranging request is that the transmission power of the embedded concealed wireless end is lower than the transmission power of the WiMAX base station. The end of the WiMAX wireless terminal is usually used with information equipment (such as a computer) = 'Or as a stand-alone use of the mobile phone. No matter how it is used, the WiMAX wireless terminal must operate in the power saving mode. Therefore, even if the melon-type WiMAX wireless terminal operates at the maximum power, it is still lower than the power of the base station. The pull-in WlMAX wireless end can't get enough reception in the upward link (the embedded WiMAX wireless ya ya, the main, the mountain fork and the cake). The electric field is in the downward chain. The towel (the towel base station is a transmitter), and the old-fashioned WiMAX line has an important state in which a sufficient receiving electric field can be obtained. Other reasons for the above problems are as follows. In the CDMA ranging request, the risk is adjusted in addition to the wattage power. Therefore, in the up-key, the signal from the W1MAX base station receiving the signal from the embedded WiMAX wireless terminal will cause the sub-channel to be dry: the two time points receive the individual influence. The singer Wang Yiren is embedded in the downward chain of WiMAX Yisuke / ...... t-end recognition prea (preamble) so that the downward chain of the knot 慎 祜 祜 挪 挪 π π 贝 抖 , , , Propagation

The delay of 2138-9878-PF 200922346 will not cause problems. On the other hand, in the upward link, WiMAX soil also uses the transmission/reception gap kp, D) to define the header of the up-key data frame according to the end of the downward link data frame. Therefore, the right is generated by propagation. The delay is too long for the WiMAX base station to receive CDMA ranging requests. In order to deduct the communication difficulty of the upward link or the low communication quality, a technique for performing a handover on a heterogeneous network (heterogeneous network) is proposed, for example, Japanese Patent Laid-Open No. 2-5 — The mobile network disclosed in the 18482 nickname, or the relay source amplified by the relay disclosed in Japanese Patent Publication No. 2006-1 96985. However, the WiMAX system has not yet implemented communication for a single down link service. In Japanese Patent No. 20 05-1 84820, it is disclosed that when a WiMM up link service is not required and only a down link service is required, a conversion (hand0Ver) is performed on a heterogeneous network. The cost of communication over the Internet is high, and the user has to pay a high communication fee. The invention disclosed in the patent No. 2006-196985 has the problem that an Anluxi relay needs investment equipment. Technology for downward link communication A wireless communication system and its retransmission control disclosed in Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. However, the invention disclosed in Japanese Patent Laid-Open No. 2003-1 53238 and Japanese Patent Laid-Open No. 8-274758 does not have a communication system for the service of the down key 2138-9878-PF 7 200922346. gp^ The method disclosed in the above-mentioned patent documents is not assumed to be used for WiMAX 。 „ 。 。. In addition, the above patent documents also do not disclose any method of linking. In addition, according to Japanese Patent Publication No. 2 -1 The downward link service disclosed in No. 53238 is limited to a broadcast channel, and thus it is difficult to apply the invention to a downward link service outside the broadcast channel. As described above, according to Japanese Patent Laid-Open No. 2m_i 53238 and Japanese Patent Publication No. 8-274758 is missing + aa looking.

Only the features, advantages and advantages of the [Embodiment] can be more clearly understood through the wireless network, and the above description is made to make the above and other aspects of the present invention It is to be understood that the preferred embodiments are as follows: Embodiments: [First Embodiment]

2138-9878-PF 11 200922346 A first embodiment of the present invention will be described below. In the WiMAX system in Figure 2, the area! The outer link can communicate with the up link and the up link, while the area 2 can only communicate with the down link. The WlMAX system of the embodiment provides only the downward link in a region, and only the downlink communication can be performed in the name region, so the individual parameters of the receiving power and the receiving timing are sufficient for the downlink communication, It is not sufficient for upward link communication. In the area 2, only the downlink communication can be performed. If the CDMA ranging is unsuccessful, the official information for entering the network (Netw〇rk Entry) other than the ranging is used for negotiation, as shown in FIG. . For the down link, the WiMAX base station 3 and the embedded WiMAX radio end 4 are directly negotiated with each other. For the upward link, the WiMAX base station 3 and the embedded WiMAX wireless end 4 are connected to each other through a heterogeneous network 9 and a connection service network (CSN) certificate authority (Certificate Authority) , CA) 6 to negotiate. The heterogeneous network 9 is a communication network, such as a third generation mobi le phone network, a second generation mobile phone network (for example, a personal digital mobile phone (personai) Digital Cellular, PDC) or Global System for Mobile Communication), Personal Handy-Phone System (PHS) network, fixed telephone network, wireless local area network (Wireiess Local Area 12

One device is connected to a heterogeneous network (heterogeneous network communicator 104), and the WiMAX communication device (WiMAX communicator 1〇3) is placed at the embedded WiMAX wireless terminal 4. These devices can be dual devices or multiple devices. CA 6 is a credential mechanism for authenticating the embedded WiMAX radio terminal 4 of the WiMAX base station 3 via the heterogeneous network 9. Access Service Network-Gateway (ASN-GW) 5 is to connect the first network (CSN 8) where CA 6 is installed to the second network (ASM 7) where WiMAX base station 3 is installed. . The ASN-GW 5 can manage all WiMAX base stations 3 and can transmit management information to each of the base stations 3 and CA 6 at predetermined intervals. If CDMA ranging is not complete, the management message for entering the network must be used to perform the negotiation instead of using ranging. For the down link, the base station 3 and the embedded WiMAX wireless end 4 are directly negotiated with each other. For the upward link, the WiMAX base station 3 and the embedded wireless end 4 are negotiated with each other via a heterogeneous network 9 with a credential mechanism 6 that connects to the service network.

That is, if the CDMA ranging is not completed, the WiMAX system performs the entry into the network and the data path according to the sequence fl〇w of Figure 4. Incomplete CDMA ranging means that parameters such as power or % order cannot be adjusted within a predetermined number of times. In the WiMAX system, the management message request and response are implemented through the heterogeneous network 9 for the upward link, thus performing the necessary negotiation g information including all the management messages except the ranging. 2138-9878-PP 13 200922346 Information, such as ss basic capabilities (basiccapabnity), registration or private key management (privacy key management).

The controller ιοί controls the operation of communicating with the wiMM wireless base station 3 of the embedded WiMAX wireless terminal 4. The parameter adjuster 2 extracts the adjustment value information contained in the ranging response received from the WiMAX base station 3 through the MAX network and adjusts the parameters for WiMAX communication based on the captured information.

The WiMAX wanted device 1〇3 is a functional unit for transmitting and receiving information through the wiMAX network. The heterogeneous network communicator 1〇4 is a functional unit that transmits and receives information through the heterogeneous network 9. The plurality of heterogeneous network communicators 1〇4 can implement at least two communication networks. Figure 6 shows the functional configuration of the WlMAX base station 3. The service line base station 3 includes a controller 2 (π, parameter determiner 2〇2, adjustment value generator 202; !, ΠΜΑΧ communicator 203, and network communicator 2〇4.

When the embedded wiMAX wireless terminal 4 enters the network (Network Entry), the DL-MAP and UL-MAP from the WiMAX base station 3 can be received through the WiMAX network (step S1). When the controller of the embedded MAX wireless terminal 4 receives the DL-MAP and UL-MAP from the wi-base station 3, the WiMAX communicator 1〇3 is used to transmit the ranging request to the WiMAX base station 3 (steps) S2).

If the shape L (a) is established, the distance or delay factor will make the evaluation of the MM base. 3 The CDMA ranging request cannot be received and the WiΜΑχ base station 3 cannot transmit the ranging response. If state (b) is established, the WiMAX base station 3 that has received the c difficult ranging request will quickly transmit the ranging response containing the adjusted value information to the embedded WiMAX wireless terminal 4 a predetermined number of times, but the embedded wireless terminal 4 cannot Adjust this value. The controller 101 of the embedded WiMAX radio terminal 4 obtains the base station identification code (1) & % stati〇n identifier, BSID) of the WiMAX base station 3 from DL - MAp. The terminal 4 uses the heterogeneous network communicator 1 to transmit the BSID of the wireless terminal 4 and the mobile station identification code (m〇bUe stai: i〇n identifier, MSID) to the CA 6 through the heterogeneous network g (step S5). ). As shown in Fig. 8, the ASN_GW 5 transmits a spare capacity request to the WiMAX base station 3 in GW5 at each predetermined interval to perform proportional resource management (rati0 res〇urce management). The spare capacity request has been received. The iWiMAX base station 3 controller 2〇1 transmits a spare capacity report to the ASN-GW 5 using the network communicator 2〇4. The spare capacity report here includes BSID information. In general, 'ASN-GW 5 transmits the latest neighbor base station resource status (neighb〇r_ bs resource status update) containing all W1MAX base station 3 information in GW 5 to all ψιΜΑχ* in GW 5

For example, the embedded WiMAX terminal 4 can include an interface unit that is coupled to other devices, such as a personal computer (PC) or a personal digital assistant (PDA). In such a configuration, 'even though the WiMAX Wi-Fi End 4 does not have multiple devices for accessing the Heterogeneous Network 9, the embedded WiMAX Wireless End 4 can communicate using the communication functions of other devices connected to the interface unit. Heterogeneous network 9 accesses CA 6 (same example as terminal 4 with multiple access devices [Second embodiment] A second embodiment of the present invention will be described below. Basically, WiMAX system configuration and first Embodiments are similar. In an embodiment where the received electric field strength and the reception timing value are insufficient to perform an upward bond and the received electric field strength is insufficient to perform a downward link, if the embedded WiMAX wireless terminal 4 responds to the WiMAx base station The BSID' of 3 must be negotiated through the management message (not the ranging) used to enter the network. As shown in Figure 10, during the negotiation process, whether it is an upward link or a downward link, WiMAX The base station 3 and the embedded wireless terminal 4 are not directly negotiated with each other but are negotiated through the heterogeneous network 9 and the CA 6 of the CSN 8. The embedded WiMM wireless terminal 4 controller ιοί can According to the received signal strength indication (Resived Signal Strength Indicati〇n, RSSI), it is determined whether the power of the lower link is sufficient for the downward link, and when the received voltage intensity is lower than the predetermined threshold, the predetermined number of times is reached.

In order to respond to the coffee, the BS D, which is a region where the power is sufficiently strong, such as a home or a common location, has been registered in advance. In addition to the downward link and the upward link, the access network in the HMAX system can be quickly changed from the heterogeneous network 9 and the (10)8 to 6 in the region where the received electric field strength is sufficient for the downward link. The network 9 performs the conversion. '[二二霄例] ^, 下下儿 The second embodiment of the invention.

The MBS includes a single BS MBS and a multiple BS MBS, and the embodiment of the present invention can be applied to the above two mbs. The service with MBS includes, for example, a broadcast channel. In order to change the content of, for example, the broadcast channel, the embedded WiMAX wireless terminal 4 controller-101 passes through the heterogeneous network "csn8 (rather than using wi· = The 'first up link' accesses the application server on the CSN 8 (not shown).
